Does anybody use wideband to tune with. I looking into buying a autometer one. Planed to run oxygen sensor in the middle of the x pipe.If anyone has pics of there please post Thanks
Where shouldit be mounted to get equal reading
Your not going to get an equal reading unless you run 2 gauges. Some guys put a bung on each side and just move the sensor around to get an idea of where the other bank is at. With fuel injection you can individually tune how much fuel goes to each cylinder "Sequential" but with a carb you will have a rough time trying to fine tune each bank. Most guys don't worry about it with a carb and just use the sensor off 1 bank of cylinders.
I don't understand this "bank to bank" thing. Carbs are not isolated on each bank. Using a 180* manifold, each side of the carb fires half the cylinders on both banks. Using a 360* manifold, the are STILL not isolated bank to bank.

For that need, perhaps best to get a wideband sensors that installs up the exhaust pipe with a temporary clamp (several kits). You need to run a cable to it, so maybe go up into the trunk and under the seats. Unlike narrow-band O2, wideband sensors control their heat so can work anywhere downstream. However, drawbacks of the rear mount are that you can't use well for close-loop control due to the time lag, and if you have any exhaust leaks that suck in outside air, you could get a false reading.Can you use the AEM/MTX-L type gauge as just a plug in tool or is something like the Innovate LM-2 the better option? I'm thinking of terms of having more than one vehicle to tune.
By sending unit heater, I presume you mean the o2 sensor.. Mine is a Bosch LS4 ( I beleive) and is heated.. It is wired through my Wideband system so that whenever the vehicle is running it received 12 volts to heat it.
I do not put power to it prior to starting.
